Introduction

DNS, or the "Domain Name
System" is the magical service behind all of the domain
names in the world that is responsible for mapping your IP address
to the domain name you choose, and magically displays your website.
It can be complicated, but our goal is to help make it easier for
you.

This guide will provide you with everything you need to know
about how the DNS works, and - more importantly - how to configure
your DNS for your website, email, and special circumstances (like
setting up subdomains). There is also a section on troubleshooting
for popular issues and a glossary of terms techies use when talking
about the DNS.
